OpenXava 4.2.3 released

Lesson 6 of OpenXava course

October 30, 2017

We're working hard to upgrade the current OpenXava course that is based in OpenXava 4 and in PDF format to use OpenXava 5 version and wiki format. We are pleased to announce that we have just finished the lesson 6, now it uses OpenXava 5 features. The lesson 6 describes custom validation methods which allow you to add specific business logic to your application.
